A nursing assistant at John Muir Medical Center in Walnut Creek was arrested last week on suspicion of the sexual battery of a patient at the hospital, police said Thursday.
Cody Baca, a 29-year-old Clayton resident, turned himself in to police last Friday after a $105,000 warrant was issued for his arrest, Walnut Creek police said.
The investigation began in October when the patient reported being a victim of sexual assault.
The Contra Costa County District Attorney's Office on Feb. 22 filed felony charges of sexual battery on an institutionalized victim and first-degree burglary against Baca, and he turned himself in a day later.
Walnut Creek police are asking anyone with information about the case to contact Detective G. Leonard at (925) 256-3523.
